"The amount of oil will not change," BP Managing Director Bob Dudley said on "Fox News Sunday." "The oil was coming out anyway from just above it at a broken area of the pipe."

But the opposite happened. Cutting the riser was supposed to allow BP to use a containment device capture more oil.

A team of independent scientists analyzed high-resolution video and found it actually made things worse, not better. Now, the scientists say, about 50 percent more oil is coming out than before. Far more than BP has been able to collect.

That means up to 100,000 extra barrels - or 4.2 million extra gallons - has gushed into the Gulf of Mexico since June 3.

BP hopes to soon double that amount of oil it contains. President Obama says it should capture 90 percent in the near future. But it's hard to have faith in the predictions when so many have been proven to be wildly off.
